Development of a Short Version of the Cataldo Lung Cancer Stigma Scale

Abstract

Lung cancer stigma is an important phenomenon experienced by many lung cancer patients that can be a barrier to medical help-seeking behavior. The purpose of this study was to shorten the Cataldo Lung Cancer Stigma Scale (CLCSS). The original 31-item scale had excellent internal consistency reliability but item redundancy. The majority of lung cancer patients are diagnosed at an advanced stage, and patient burden with survey completion may be higher in this population. To reduce patient burden with participation in lung cancer stigma-related research, a psychometrically sound short measure of lung cancer stigma is valuable. Factor analysis was used to evaluate the dimensionality of the CLCSS. Results were used to shorten the measure to 21 items. The shortened scale showed strong evidence of internal consistency reliability (Cronbach's alpha =.93). Results also indicate the scale is three dimensional with reliable subscales: stigma and blame, social isolation, and discrimination.
